Easy to Operate – Safe. Comfortable. Efficient.

Ensuring operators are safe, confident in the control of their machines, have a clean, comfortable and quiet operating environment with controls that are intuitive and low effort all contribute to lower operator fatigue and better performance.

Cab Access

A switch has been added to the electronic service center which unlatches the door remotely (optional). The gas strut then swings the door open all while the operator is safely on the ground. The angle of the steps up to the cab have been increased to an optimal fifteen degrees enabling operators to walk up like stairs versus climbing more vertically like a ladder. Grab handles have been repositioned so a secure three points of contact can be maintained at all times.

Visibility

Once in the cab, the new door securely seals against the new roll formed ROPS posts and the lower glass panel has been extended several inches to improve visibility to the left side of the machine. New larger convex mirrors improve visibility to the rear and integrated spot mirrors provide visibility close to both sides of the machine.

Sound

Viscous cab mounts connect the cab to the frame of the machine, decreasing noise and vibration the operator is subjected to. The result is a sustainable work environment and well-rested operator, remaining efficient and productive.

Central Display

The central display panel has a large text box, analog gauges, and LED warning indicators. The large text box provides in-language information about machine operation, feature activation and system troubleshooting and calibration. With the large analog gauges the operator can easily identify if key systems are within normal operating range.

Control Panel

Sealed against moisture and dirt, the centralized switch panel with LEDs provides reliability and ready access to frequently required functions, even while wearing gloves. The ISO symbols located on each membrane switch are molded all the way through to ensure the image will not wear off over time.

The M Series maintains the “help” feature which explains the function of each membrane switch.

Focusing on operator efficiency, the control panel has been streamlined to include easy to reach highly utilized machine controls. The touch screen display enables the relocation of some expanded functions while eliminating the need for a second switch panel for further simplicity and easy machine operation.

Steering Wheel

The steering configuration on these machines offers a low-effort hand metering unit hydraulic steering system. Load sensing steering directs power through the steering system only when needed.

Implement Controls (EH)

Seat-mounted, single axis implement control levers (joysticks, optional) provide operators with precise control of the work tool, all while moving with the seat for maximum comfort. In-cab, programmable kick-outs and automatic cylinder snubbing are easy to set on-the-go for tilt, lower and lift, and are ideal for repeatable cycles.

Ride Control

The next generation of ride control works as a shock absorber, improving ride quality and smoothness over rough terrain, increasing operator confidence, comfort and efficiency, ensuring excellent material retention.

Cooling System

An optional variable pitch fan automatically purges the cooler cores by periodically reversing the airflow when needed. This fan is beneficial in providing more airflow in the reverse direction (when compared to a system that simply reverses the fan rotation), which more thoroughly expels any debris build-up in the cooling cores. The variable pitch fan reduces the need for an air wand used to clean the backside of the cooler cores. For very high debris applications often found in millyards, consider pairing the variable pitch fan with optional high debris cooling cores for a robust solution and reduced maintenance.

An optional axle oil cooling system provides the capability to dissipate heat generated in high energy applications, such as braking with a large load or extended roading.

Air Systems

In conjunction with the standard strata precleaner, the optional turbine engine precleaner extends filter element life and helps to provide clean air to the engine in high debris applications by ejecting saw dust and similar material before it ever reaches the air cleaner. Similar in function, a Cat Advanced Cabin Filtration (ACF) precleaner is also available to extend service intervals of the cabin filter.

Guarding

Depending on the level of protection required, three optional guard designs are available to help protect the cab glass from damage while working in tough forestry applications. There are two front windshield guard options and a full cab glass guarding option available. Protecting the underside of the machine, the power train guard prevents debris build-up and damage to major components or systems such as the engine or transmission.

Cooling System

The cooling system is readily accessible for clean out and maintenance. With nine cooling fins per 25.4 mm (1.0 in) and a perforated grill, most airborne debris entering the system passes through the cooler cores. The hydraulic and A/C cooler cores swing out providing easy access to both sides for cleaning. An access panel on the left side of the cooling package swings down to provide access to the back side of the engine coolant and Air-to-Air After Cooler (ATAAC). An optional variable pitch fan can automatically purge the cooler cores by periodically reversing the airflow when needed.

Service Centers

The electrical and hydraulic service centers provide grouped access to numerous features, enhancing safety and convenience for your operators and service technicians, while reducing service time.

Hydraulic system components are protected by full flow and kidney-loop filtration. A filter in the hydraulic tank return line filters all of the oil returning to the tank. There is also a case drain screen for additional protection and finally, a separate kidney-loop filter with a finer micron rating continuously filters smaller particles out of the system. This multilevel design ensures the hydraulic oil is clean and thoroughly protects the rest of the hydraulic system from contamination. A thermal bypass valve has been added to improve hydraulic system warm-up.

The hydraulic service centers are now virtually identical for the M Series product line. This consistent layout makes it easier for service technicians who work on a variety of M Series models.
